You most probably do, this is a foundation for chemistry and without it you wont be able to tackle the harder parts of chemistry. I was a bit like you and couldn't be bothered to learn it. However, just sit down and take 30 minutes to remember it. It's really not that difficult and when you just sit down and learn it you'll realise it's fairly simple as it's very logical in nature.

I have already for aqa it doesn't say. roughly how many are there to remember for edexcel?

11. understand reasons for the shapes of, and bond angles in, simple molecules and ions with up to six outer pairs of electrons (any combination of bonding pairs and lone pairs) Examples should include BeCl2, BCl3, CH4, NH3, NH4 +, H2O, CO2, PCl5(g) and SF6(g) and related molecules and ions; as well as simple organic molecules in this specification.

straight from the spec

also:
12. be able to predict the shapes of, and bond angles in, simple molecules and ions analogous to those specified above using electron-pair repulsion theory
